TO ALL WHOM IT MAY CONCERN:

Be it `known that I, N. BANGS WILLIAMS, ofthe city and county ofProvidence, in the State of Rhode Island, have invented e certain newand useful Improvement in Oil-Cups for lubricating machinery; and I dohereby declare that the following specification, taken' in connectionwith the drawings, making a, part of the same, is a. full, clear, andexact description thereof. i

My invention consists in combining with a` chambercontnining a. suitablefibrous absorbent, through which absorbent the oil must fiow, in itspassage to the part of the machinery to be lubricated, a conicalortapering compressing-plug, arranged to act upon the absorbent in suchwey that the density of the mass can he`regulated at pleasure, to varythe rute at which the oil shall be transmitted through it, and isparticularly adapted to pillow-blocks,'spindle-holsters, &c.

The mere usc of un absorbent and a compressing-plug, in connection withan oil-chamber, is known to me.

to have been used before, and is therefore not claimed by me. Thepeculiar .forni of my compressing-plug is new and valuable, -as by itsmovernent downward the density of the packing or absorbent is increasedJby a.

-lateral as well as a perpendicular pressure, end working nearly thesame variation es to the How of oil, by a.

single turn of the screw, as would be e'ected by many -turns of thescrew in any of the before-known forms of plug used in the sameconnection. In the amended drawing- Figure 1, A represents the reservoirfor oil; B, a chamber in which the'brou's absorbent is placed. The ductsthrough which the oil passes from A to B, are clearly shown, being, inthis instance, perpendicular slots. b is the conducting-tube or passage,through which the oil Hows to the lubricating part. a is the conical ortapering plug, wherein my improvement rests.

Figure 2 is e top view thereof.

' I cloim asvmy own invention* The tapering compressing-plug a,- iucombination with a chamber, B, containing a. iibrous` absorbent, for

the purposes specified.
